The advent of the study of two–dimensional layers with atomic thickness
has renewed the interest in transition–metal dichalcogenides (TMDs)
and their optical/optoelectronic properties [1]}. These
materials, which have been studied in their bulk form since the 1960's
[2]}, [3]}, have been shown to be good candidates for
various optical and optoelectronic applications [4]}, [5]}, [6]}, [7]}.
